Lanthanum Hexaboride Rod Description

Lanthanum Hexaboride Rod (LaB6 Rod) is an inorganic chemical. With melting point 2528 K, LaB6 is a refractory ceramic material, which is insoluble in water or hydrochloric acid and very stable in a vacuum. Stoichiometric samples are colored intense purple-violet, while boron-rich ones (above LaB6.07) are blue. Ion bombardment changes its color from purple to emerald green. LaB6 is a superconductor with a relatively low transition temperature of 0.45 K.

FAQs

1. What are LaB₆ rods used for?

Electron sources in SEM, TEM, X-ray tubes, and e-beam equipment.

High-temperature cathodes with low work function (~2.6–2.8 eV).

Thermal or electrical components in vacuum or plasma systems.

2. How to store and handle LaB₆ rods?

Store in dry or inert atmosphere, away from moisture.

Avoid touching or contaminating the emitting surface.

Handle gently — material is brittle.

Use in clean, high-vacuum environments for best performance.
